Ira & Larry Goldberg Coins & Collectibles, Inc.'s "Benson Collection, Part
I", February 16, 18-20, 2001, lot 1092, illustrated, where it was
described as follows: "Bronze, no "L"…A very important coin as a one-year
type, the type of 1860 - 1864 struck in the new bronze alloy. This example
had until recently been tied with one other example as the finest graded
by PCGS. The coin has outstanding deep mirrors with frosted devices and
essentially perfect surfaces. The coin has acquired a beautiful golden
color with the passage of time. This is one of the rarest dates in the
proof Indian Cent collection.

The mintage of 1864 proof cents is open to some debate. Breen recorded a
total of 470 proof sets of the silver and minor coins sold by the Mint. He
breaks down the deliveries to those made before the Mint Act of April 22
as the mintage of the copper nickel examples (370) and those after as the
mintage of the bronze No L pieces (100). This cannot be correct, since
there are nearly 200 1864 No L proofs graded from all the grading services
combined. There must have been an unknown number of specimens made and
distributed later in the year. Up until this time, and continuing until
1878, the mintage figures of minor coins must be reconstructed from sales
figures of sets and any other collateral evidence that can be found. The
Mint was under no legal obligation to record mintage figures for minor
coin proofs. We can guess at the original figures based on what we see in
the marketplace, accounting for a quantity of examples being lost to the
ravages of time, but even an educated guess will undoubtedly be off the
mark. Regardless, perhaps 300 is the correct mintage. Color photo.",
